A team of researchers has found that consuming an omega-3 fatty acid called DHA, or docosahexaenoic acid, can stop a known trigger of lupus and potentially other autoimmune disorders. DHA can be found in fatty, cold-water fish and is produced by the algae that fish eat and store in their bodies. It can be found in fish oil supplements as well, used by more than 30 million Americans.
Children with HIV who can resist the disease progressing could point the way to new treatments for HIV infection that are more widely applicable to infected adults and children alike, an international team of researchers has found.
A team of researchers has observed what they believe are the building blocks of memories in a mouse brain. In their paper, the researchers describe how they caused certain neurons to become illuminated when they fired, allowing them to watch in real time as memories were made and then later as they were replayed while the mouse was sitting idle.
Why do more men die when they attempt suicide than women? The answer could lie in four traits, finds scientists. There are over 6,000 British lives lost to suicide each year, and nearly 75 per cent of those are male. However, research has found women are more likely to suffer from depression, and to attempt to take their own life.
Researchers studying how the brain uses perception of the environment to guide action offer a new understanding of the neural circuits responsible for transforming sensation into movement.
Using archival documents, a new report examines the sugar industry’s role in coronary heart disease research and suggests the industry sponsored research to influence the scientific debate to cast doubt on the hazards of sugar and to promote dietary fat as the culprit in heart disease.
It’s advice most smokers with children probably take lightly, but they shouldn’t. Parents and policy advocates should take a “zero tolerance” approach to exposing children to secondhand cigarette smoke, which can be responsible for lifelong cardiovascular consequences in addition to respiratory and other health issues.
Household dust exposes people to a wide range of toxic chemicals from everyday products, according to a new study. A multi-institutional team conducted a first-of-a-kind meta-analysis, compiling data from dust samples collected throughout the United States to identify the top ten toxic chemicals commonly found in dust.
Typically when scientists make a measurement, they know exactly what kind of measurement they’re making, and their purpose is to obtain a measurement outcome. But in an “unrecorded measurement,” both the type of measurement and the measurement outcome are unknown.
Scientists trying to find ways to regenerate a damaged heart have shed more light on the molecular mechanisms that could one day make this a reality. Whilst other organs such as the liver can regenerate, the heart muscle has very little ability to do so after suffering damage, such as a heart attack.
In the womb the body is able to produce heart muscle cells but soon after birth it effectively stops producing them.
According to new research, widespread adoption of genetically modified crops has decreased the use of insecticides, but increased the use of weed-killing herbicides as weeds become more resistant. This is the largest study of genetically modified crops and pesticide use to date. The team of economists studied annual data from more than 5,000 soybean and 5,000 maize farmers in the U.S. from 1998 to 2011, far exceeding previous studies that have been limited to one or two years of data.
A trio of researchers has found off-the-shelf AI software can be used to identify people in blurred or pixilated images. The researchers have uploaded a paper describing the experiments they carried out with AI software identification of people or other items in blurred out images, what they found and reveal just how accurate they found it could be.
As you relax and let your mind drift aimlessly, you might remember a pleasant vacation, an angry confrontation in traffic or maybe the loss of a loved one. And now a team of researchers say they can see those various emotional states flickering across the human brain.
Saving up excess solar and wind energy for times when the sun is down or the air is still requires a storage device. Batteries get the most attention as a promising solution although pumped hydroelectric storage is currently used most often. Now researchers are advancing another potential approach using sugar alcohols—an abundant waste product of the food industry—mixed with carbon nanotubes.
Training the brain to treat itself is a promising therapy for traumatic stress. The training uses an auditory or visual signal that corresponds to the activity of a particular brain region, called neurofeedback, which can guide people to regulate their own brain activity. However, treating stress-related disorders requires accessing the brain’s emotional hub, the amygdala, which is located deep in the brain and difficult to reach with typical neurofeedback methods.
A tiny RNA appears to play a role in producing major depression, the mental disorder that affects as many as 250 million people a year worldwide. Major depression, formally known as major depressive disorder, or MDD, brings increased risk of suicide and is reported to cause the second-most years of disability after low-back pain.
New research has shown that the corticosteroid deflazacort is a safe and effective treatment for Duchenne muscular dystrophy. The findings could pave the way for first U.S.-approved treatment for the disease.
Most people remember where they were when the twin towers collapsed in New York … new research reveals why that may be the case. The study has shed new light on the biological mechanisms that drive the process, known as flashbulb memory.
Researchers have found links between the levels of antimicrobial chemicals and antibiotic-resistance genes in the dust of an aging building used for athletics and academics. One of the antimicrobials seen in the study is triclosan, a commonly used antibacterial ingredient in many personal care products.
Electronics integrated into textiles are gaining in popularity: Systems like smartphone displays in a sleeve or sensors to detect physical performance in athletic wear have already been produced. The main problem with these systems tends to be the lack of a comfortable, equally wearable source of power. Chinese scientists are now aiming to obtain the necessary energy from body heat by introducing a flexible, wearable thermocell based on two different gel electrolytes.
With nearly sixty percent of American adults now taking prescription medications–from antidepressants to cholesterol treatments–there is growing concern about how many drugs are flowing through wastewater treatment facilities and into rivers and lakes. Research confirms that pharmaceutical pollution can cause damage to fish and other ecological problems–and may pose risks to human health too.
Parents who excel at math produce children who excel at math. This is according to a recently released study, which shows a distinct transfer of math skills from parent to child. The study specifically explored intergenerational transmission–the concept of parental influence on an offspring’s behavior or psychology–in mathematical capabilities.
Can life be brought to celestial bodies outside our solar system, which are not permanently inhabitable? A new essay that has been published is trying to deal with this question. Over the last several years, the search for exoplanets has shown that very different types exist leading to new questions and a variety of possible answers.
At the dinner table, babies do a lot more than play with their sippy cups, new research suggests. Babies pay close attention to what food is being eaten around them – and especially who is eating it. The study adds evidence to a growing body of research suggesting even very young children think in sophisticated ways about subtle social cues.
The children of traumatized people have long been known to be at increased risk for posttraumatic stress disorder (PTSD), and mood and anxiety disorders. However, there are very few opportunities to examine biologic alterations in the context of a watershed trauma in exposed people and their adult children born after the event.
